Unix Editors
- What is a text editor?
- A text editor is a program which enables you to create and manipulate character data (text) in a computer file.
- A text editor is not a word processor although some text editors do include word processing facilities.
- Text editors often require "memorizing" commands in order to perform editing tasks. The more you use them, the easier it becomes. There is a "learning curve" in most cases though.
- There are several standard text editors available on most UNIX systems:
- ed - standard line editor - interactive, buffered, line oriented
- ex - extended line editor
- vi - a visual editor; full screen; uses ed/ex line-mode commands for global file editing - interactive, buffered, screen oriented
- sed - stream editor for batch processing of files - non interactive, non-buffered, stream oriented
- vim - upgraded version of vi
- xemacs - popular open source editor
- In addition to these, other local "favorites" may be available:
- emacs - a full screen interactive editor and much more
- nedit - another GUI style text editor similar to emacs.
- pico - an easy "beginner's" editor
